my fellow gropers are sort of right.
Drive West hit the coast, swim, surf, then south and have a coffee in Fremantle.
Drive east along canning highway and if you see the river turn left and drive along it- you may spot a windsurfer or two.
Continue east- hit the freeway and go north,
cross a bridge and see the hill on the left- get off freeway and make your way to Kings park- nice view, expensive coffee.
hit the tom tom to Subiaco or trendy Leederville for a coffee, bookshop and shopping for the Mrs.
Back on the freeway north to Joondalup
if you see bunnings you are in Joondalup- just follow the utes.
If you like a good meal and early lights out "Hoon" up the freeway and you will get yourself in Jail, I recommend 110 in the 100 zone.
So that will take about 1/2 an hour, Hotel mini bar drunk for the rest of the day
